>The code works great! But how can I update or delete the key! I have tried wrting the key again with a different value, but I don't think that is the correct way

Function DeleteRegistry
   Lparameters tcRegistryKey
   * tcRegistryKey = registry key to delete
   * ex: "HKCC\System\CurrentControlSet\Control\Print\Printers\Default"
   oShell = Createobject("WScript.Shell")
   lcValue = oShell.RegDelete(tcRegistryKey)

Note: you must delete keys one at a time. In the example above delete in this order:
HKCC\System\CurrentControlSet\Control\Print\Printers\
HKCC\System\CurrentControlSet\Control\Print\
HKCC\System\CurrentControlSet\Control\

Note: the backslash at the end indicates a key (rather than a value)

use the .Regwrite() function to update.
